Description

TERMINAL FOR VEHICLE}

The present invention relates to a vehicle terminal, and more specifically, by fixing a male magnet to a male terminal and fixing a female magnet to a female terminal, so that the male magnet and the female magnet come into contact with magnetic force to guide electricity supply to the male terminal. This relates to a vehicle terminal intended to prevent poor assembly and assembly defects due to insertion force between terminals when a terminal is inserted into a female terminal.

In general, connectors are widely used as an electrical connection means in various electrical devices used for industrial purposes as well as home appliances used at home.

In the case of automobiles, many connectors are used to connect electrical components, controllers, batteries, etc., and various types of connectors are used depending on current capacity.

Common connectors for connecting wires are divided into a female connector and a male connector, and electrical connection is made by fastening between the female connector and the male connector.

In addition, the female and male connectors have a structure in which terminals to which wires are connected are assembled inside a connector housing, and when the housings of the female and male connectors are coupled, the female terminal and the male terminal are connected so that electricity can be passed to each other.

Conventionally, various types of connector terminals have been used depending on the current capacity used in the electrical system, but recently, there has been a demand for technology development that can realize standardization, commonization, miniaturization, and weight reduction of connector terminals.

Terminals used in female connectors, that is, conventional female terminals, range from a simple form in which a wire is pressed to a barrel to a form that uses a conductive part that can accommodate a high current using a raw material alloy system with high conductivity, and a form that uses a conductive part that can accommodate a high current. A form employing a tension part (spring) is known.

The background technology for the present invention is disclosed in Korean Patent Publication No. 10-2014-0008879 (publication date: 2014.01.22.) “Connector terminal with improved insertion and coupling properties.”

The above-described technical configuration is background technology to aid understanding of the present invention, and does not mean that it is widely known prior art in the technical field to which the present invention belongs.

Automotive connectors according to the prior art apply a spring contact structure to ensure the safety of energization when combining the female terminal and the male terminal, so insertion force and contact pressure are inevitably generated, but the terminal size (volume) is reduced due to high voltage use. As the insertion force and contact pressure increase, the increase in insertion force and contact pressure becomes larger, which causes a problem in that the assembly efficiency of inserting and assembling the male terminal into the female terminal is deteriorated.

Therefore, there is a need to improve this.

The present invention was devised to improve the problems described above. By fixing a male magnet to a male terminal and fixing a female magnet to a female terminal, the male magnet and the female magnet are brought into contact with magnetic force to guide electricity supply. The purpose is to provide a vehicle terminal to prevent assembly defects and deterioration of assembly due to insertion force between terminals when the male terminal is inserted into the female terminal.

A vehicle terminal according to the present invention includes: a female terminal; a male terminal adjacent to one side along the axial direction of the female terminal to enable electricity to pass through; and an end contact portion that maintains a simple contact state between one side of the female terminal and one side of the male terminal along the axial direction.

The end contact part is fixed to one side along the axial direction of the female terminal and includes a female magnet contact part that generates magnetic force to induce contact with the corresponding male terminal.

The female magnet contact unit includes female side wings extending from one side to both sides of the female terminal; a female magnet that is wrapped and fixed to the female terminal and the pair of female side wings and is magnetic; And a point contact guide for ensuring contact reliability while reducing the contact area with the male terminal by the magnetic force of the female magnet.

The end contact part is fixed to one side along the axial direction of the male terminal and includes a male magnet contact part that generates magnetic force and comes into contact with the point contact guide part to induce electricity supply between the female terminal and the male terminal.

The point contact guide unit includes an opening formed in the female magnet; a contact pin that is axially inserted into the opening and contacts each other by magnetic force to directly transfer the magnetic force of the female magnet to the corresponding male terminal; and a stopping pad provided on one side of the female terminal, supporting the contact pin inserted into the opening, and having a communication hole to guide a portion of the contact pin to protrude outward.

The point contact guide includes an elastic spring that elastically supports the contact pin toward the stopping pad while being inserted and fixed into the opening.

The female magnet is characterized in that a female supporter is provided on the other side of the female side wing to contact and support the other side of the female magnet.

The mail magnet contact unit includes a mail side wing extending from one side of the mail terminal to both sides; and a magnetic male magnet that is wrapped and fixed to the male terminal and the pair of male side wings and exerts an attractive force on the corresponding female magnet.

The mail magnet contact portion includes a mail elastic pad that extends to be elastically deformable from one side of the mail terminal or one side of the mail side wing and elastically contacts the mail magnet.

As described above, the vehicle terminal according to the present invention, unlike the prior art, fixes the male magnet to the male terminal and the female magnet to the female terminal, so that the male magnet and the female magnet contact by magnetic force to conduct electricity. By providing guidance, it is possible to prevent assembly defects and deterioration of assembly due to insertion force between terminals as the male terminal is inserted into the female terminal.
